Ihor Solodrai	bd06b977e0	selftests/bpf: Migrate struct_ops_assoc test to KF_IMPLICIT_ARGS ... A test kfunc named bpf_kfunc_multi_st_ops_test_1_impl() is a user of __prog suffix. Subsequent patch removes __prog support in favor of KF_IMPLICIT_ARGS, so migrate this kfunc to use implicit argument.

Amery Hung	04fd12df4e	selftests/bpf: Test ambiguous associated struct_ops ... Add a test to make sure implicit struct_ops association does not break backward compatibility nor return incorrect struct_ops. struct_ops programs should still be allowed to be reused in different struct_ops map. The associated struct_ops map set implicitly however will be poisoned. Trying to read it through the helper bpf_prog_get_assoc_struct_ops() should result in a NULL pointer. While recursion of test_1() cannot happen due to the associated struct_ops being ambiguois, explicitly check for it to prevent stack overflow if the test regresses.
